Accelerator-pedal module
Accelerator-pedal module APM
The air and fuel systems of gasoline engines prepare
an air-fuel mixture which allows the engine to generate
the required torque. Simultaneously, this mixture also
fulfills further requirements, for example from the
exhaust system. The electronic engine control adjusts
the ideal air-fuel ratio and the optimal injection timing.
The engine control evaluates sensor signals from the
entire drivetrain and the exhaust system, prioritizes
them and converts them into control commands.
Task
The driver’s requirement for more or less torque is a
key input variable for controlling the air charge electronically. The accelerator-pedal module provides this
